TUBE-TECH a Classic Brand

Electronics designer John G. Petersen shipped the first PE1A program EQ's in June 1985.

John was inspired by the principles behind fine classic tube-based processors, such as Pultec and Teletronic. Since then, and throughout the intervening years, John has created a wide range of TUBE-TECH units, now considered classics in their own right.

TUBE-TECH gear has played, and continues to play, a very important role in thousands of recordings worldwide. So many well-known global hits have been either been recorded with, and/or performed on, TUBE-TECH units that we have literally lost count.

TUBE-TECH represents the pinnacle of audio production and musical sound shaping. The “Blue Gear” continues its decades-long leadership, impervious to trends, technology, and competition.

TUBE-TECH Design

"Simply put, tubes sound pleasant to the ear. They treat signals with respect.

But perhaps more profoundly they place serious constraints on how much circuitry you can build into a unit.

With solid-state design, an engineer is free to ad circuitry with very little penalty, which can start you down the road of "fixing" percieved faults in the design with even more circuitry.

Unfortunately, the end result is usualy something that sounds worse than if the original circuit had been improved from the start.

As a result, I have to design very simple circuits.

There's no "patch" I can use to fix a circuit's faults. It has to stand by itself."

A New Way of EQ'ing

HLT2A - Available Now!

The TUBE-TECH HLT 2A is an all-new kind of Equalizer, combining High and Low shelving Eq plus Hi and Low cut filters with an innovative T filter “tilt” midrange Eq.
It's the first time this combination of filters has been designed in the analog domain.

The shelving EQ's are designed around a high gain tube amplifier, and the T- filter and Hi/Lo filters are passive filters placed after the active shelving EQ and before the output amplifier. All sections are supplied with a bypass switch.

The HLT2A furthermore features an overall bypass switch.

So how does it sound?

The TUBE-TECH HLT 2A marks a different approach to EQ'ing. It is a very powerful overall shaping EQ, yet extremely simple to operate.

To put it simply, the HLT2A will yield good results for basically any material and application, ranging from the demanding mastering engineer to the sound quality hungry project studio owner.
The combination of Hi and Lo shelf and Lo/Mid frequency T just creates a ton of very nice EQ shaping possibilities!

Mastering Version

John G Petersen is working on a mastering version of the HLT2A with stepped pots and a smaller and more detailed range for the shelf and T- filter EQ. This will be released in early 2016.
